Cycle Service:

> Avoid battery over discharge, especially battery sereis connection use. > There are a number of factors that will affect the length of cyclic service.

> Charged with recommend voltage, ensure battery can be full recharged. The most significant are depth of discharge, ambient temperature,

In general, recharge capacity should be 1.1-1.15 times discharge capacity. discharge rate, and the manner in which the battery is recharged.

> Effect of temperature on float charge voltage: -4mV/°C/Cell. Generally specking, the most important factors is depth of discharge.
